Part Number: TPSM53604

Hi,

I will plan to use TPSM53604 for negative output. Refer to the document as below. I am no idea about the value of Cbulk. Would you help to suggest the better value of Cbulk?

Thanks,

    Hi Chen,

    You can use a 100uF bulk cap with high ESR (10-30mOhm). This will help dampen input voltage ripple and any noise that is a result of having long input leads. 

    Here's an example of a 100uF bulk cap ().
